The doorstep to the temple of wisdom is a knowledge of our own ignorance
Only the wisest and stupidest of men never change.
To acquire knowledge, one must study; but to acquire wisdom, one must observe.
Marylin vos Savant
Science is organized knowledge. Wisdom is organized life.
Knowledge comes, but wisdom lingers.
Alfred Lord Tennyson
Wisdom is not a product of schooling but of the lifelong attempt to acquire it.
